We broke down the feeding assay with Diopatra, Ulva, and the chemical extracts of Gracilaria! We found that there was no difference in the amount of Ulva the worms ate with Gracilaria chemicals painted on it and without Gracilaria chemicals. This tells us that the Gracilaria chemicals may not be preventing the worms from eating it. These results do not explain why the worms do not like to eat Gracilaria, so there are still questions to be answered!
